General Description

The DS3502 is a 7-bit, nonvolatile (NV) digital potentiometer (POT) featuring an output voltage range of up to 15.5V. Programming is accomplished by an I2C-compatible interface, which can operate at speeds of up to 400kHz. External voltages are applied at the RL and RH inputs to define the lowest and highest potentiometer outputs.
